Evidence of viral adaptation to HLA class I-restricted immune pressure in chronic hepatitis C virus infection [PDF]

open access: yes, 2006
Cellular immune responses are an important correlate of hepatitis C virus (HCV) infection outcome. These responses are governed by the host's human leukocyte antigen (HLA) type, and HLA-restricted viral escape mutants are a critical aspect of this host ...

Evaluation of Antihemagglutinin and Antineuraminidase Antibodies as Correlates of Protection in an Influenza A/H1N1 Virus Healthy Human Challenge Model

open access: yesmBio, 2016
Despite long-term investment, influenza continues to be a significant worldwide problem. The cornerstone of protection remains vaccination, and approved vaccines seek to elicit a hemagglutination inhibition (HAI) titer of ≥1:40 as the primary correlate ...

The effect of calcium and magnesium on activity, immunogenicity, and efficacy of a recombinant N1/N2 neuraminidase vaccine

open access: yesnpj Vaccines, 2021
Despite the importance of immunity against neuraminidase (NA), NA content and immunogenicity are neglected in current influenza vaccines. To address this, a recombinant N1/N2 NA vaccine (NAV) was developed. Stability assays were used to determine optimal

Viral entry and escape from antibody-mediated neutralization influence hepatitis C virus reinfection in liver transplantation [PDF]

open access: yes, 2010
End-stage liver disease caused by chronic hepatitis C virus (HCV) infection is a leading cause for liver transplantation (LT). Due to viral evasion from host immune responses and the absence of preventive antiviral strategies, reinfection of the graft is

Widespread and dynamic expression of granzyme C by skin-resident antiviral T cells

open access: yesFrontiers in Immunology, 2023
After recognition of cognate antigen (Ag), effector CD8+ T cells secrete serine proteases called granzymes in conjunction with perforin, allowing granzymes to enter and kill target cells.

A multi-variant, viral dynamic model of genotype 1 HCV to assess the in vivo evolution of protease-inhibitor resistant variants [PDF]

open access: yes, 2010
Variants resistant to compounds specifically targeting HCV are observed in clinical trials. A multi-variant viral dynamic model was developed to quantify the evolution and in vivo fitness of variants in subjects dosed with monotherapy of an HCV protease ...

Evolution of lamivudine resistance in human immunodeficiency virus type 1-infected individuals:the relative roles of drift and selection [PDF]

open access: yes, 2000
Human immunodeficiency virus type 1 (HIV-1) rapidly develops resistance to lamivudine during monotherapy, typically resulting in the appearance at position 184 in reverse transcriptase (RT) of isoleucine instead of the wild-type methionine (M184I) early ...

An adjusted ELISpot-based immunoassay for evaluation of SARS-CoV-2-specific T-cell responses

open access: yesBiosafety and Health, 2022
Like antibody evaluation, using an effective antigen-specific T-cell immunity assessment method in coronavirus disease 2019 (COVID-19) patients, survivors and vaccinees is crucial for understanding the immune persistence, prognosis assessment, and ...

Retrospective Analysis of Donor Lymphocyte Infusions in Pediatric Patients With Mixed Chimerism After Hematopoietic Stem Cell Transplantation

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Allogeneic hematopoietic stem cell transplantation (alloHSCT) is an essential therapy for several malignant and nonmalignant diseases, but relapse and graft loss remain the principal threats to its success. Routine monitoring of chimerism and minimal residual disease (MRD) enables early detection of imminent recurrence and guides ...

Genotype-by-inhibitor interactions to dissect enterovirus replication

open access: yesNature Communications
Replication organelles of positive-sense RNA viruses are essential to virus biology, yet their molecular mechanisms remain poorly defined. While deep mutational scanning (DMS) measures the impact of mutations across viral proteins, it cannot resolve ...
